Siouxsie Sioux She was the youngest of three children, born at Guy's Hospital in South London. She attended Mottingham Secondary Modern School for Girls in Kent. Her mother was a bilingual secretary, her father a laboratory technician who milked serum from poisonous snakes. When Sioux was 14, her father died from complications of alcoholism. At age 15, she suffered ulcerative colitis, an experience she described later as "surreal." Later she stated that "it completely de-romanticised the body for me."
While growing up, Sioux was often left to look after herself in an undisciplined atmosphere. Even before his death, her father's alcoholism kept him incapacitated, forcing her mother to work full time. Even the garden at their home north of Petts Wood grew into a jungle, with high hedges and rambling roses, until the neighbours complained.
During her teens, she was a self-confessed loner and started getting into music like David Bowie, Lou Reed, T Rex and The Stooges. She became very well known in the London punk scene for her outragous glam, fetish and bondage attire, which became staples of punk fashion.
